The MAX4659/MAX4660 are medium voltage CMOS analog switches with a low on-resistance and high switch current capability. They can replace reed relays with faster switching speed and longer lifetime cycles. These analog switches have low power consumption and can operate within a wide power-supply range.
The MAX4659 and MAX4660 are medium‑voltage CMOS analog switches designed for high current handling. They feature a low on‑resistance of 25 Ωmax, support up to 200 mA peak current (MAX4660) or 150 mA (MAX4659), and provide rail‑to‑rail signal handling with only 1 nA off‑leakage current.
The devices operate from dual supplies of ±4.5 V to ±20 V or a single supply of +9 V to +40 V, and are available in 8‑pin µMAX and SO packages. Detailed electrical characteristics, pin configurations, and typical performance graphs are included for design reference. This manual is written in Chinese.
